To all-15710111 it may Concern Beitlanown that l, HENRY HART,.olletrait, in the county of ll'nyne and State ot" Michigan, lieveinvented en. linprm'ement in Ny invention relates to new 4and usefulimprovements in cnrpet-sweepers,l byv menus ot' which economy inConstruction. is combined with the requisite strength und durability.Hence my invention Consists in the peculiar di.

is of construuion ot' the various pau-ts, then various combinations :1ndoperation, as more fully hereinafter descr-i bed.

in theareeonipnnying drawings, which form e part of this specification,A represents a shell f meile of steamed sind bent wood, orming the topand sides, and B B :ire the ends, also made of' wood and secured withinthe ends et the shell. This latter is made :is described, in order to besulieiently strong; to oilow the handle attachments to be securedthereto, instead, :is

'where the shell is made of tin or thin sheet metal, ofheing compelledto secure the handle to the ends of the device by means ot' a bail.

CG are a. pair of wheels secured to short ehaite properlyjonrnaled inthe end B :1nd between it. and the metal partition l).

Dailey, E, is secured to a shaft whieh iorzrnaled in a. standard, l".This standard is nred to the inner face of the end Il', so :is tz.: herea. vertical adjnstubility by means oi' sot-screw a, which passesthrono': the shell. The inner end oi' this pulley projects through theslot l), and its projecting end c is polygonal in form to eng-.ige witha similarly shaped socket. in 'the head d, which is secured en the endofthe brnsltshaft G.

A. bood or heit, il, passes over and under the wheels C and over thepulley E, and :is

l i l these wheels are the traction-wheels ofthe sweeper, theirrotation, by meiins ot' the belt, gives the necessary rotation to the`brushshnft.

The head d is made ot' malleable metal, and is provided with two or moreears, e, which,

embrace the sides ofthe wooden shaft (l and the hond is secured in pinceby turning: the endso' such lnrA into the sides ot' the shaft, :is shownin lig'. 5. The opposite end of this shalt (l is provided with :i pintleor journal, h, which rests in n suitable hole or indentation in thebell-eranloshnped support l. This snpport is supported through the top Aby means ot the set-'screw i, by means of which, also, the

support. is vertically mlju'stnble. The longterm ot' the support isforced toineline inwardly, by ineens ot'n spring, s.

".'fhen it is desired, t'or any purpose, to remove. the hriislx, thelong arm of the support is forced against the end B, and this engagesthe journal if., which ,allows the shaftto be drawn toward the end B,and this disengages the head i? from the end. of the shaft; whichcarries the pulley E;

. .l nre. two dust-receivingpans, one on each side of the brush. andtheyiire, alike in construction and operation. A description ofone ofthem will be snilieient for the purposes of 8o this speciiicntion. Thefree or front edge of the pon is mode with two inclined or beveledsidesa a", the latter of which facilitates depositing the dirt in thepan by the brnsh,whiie the former facilitates the dirt leavingt'he pan Ywhen it is d um pecl. The pan is provided at; each end with n journal orpintle, m m', the former engaging' with the hole n n in the' plate D,.while the latter engages with a recess, o o, in; the head B. The-pintle m'. is also provided with a. coil-spring, r, one end of whichrests against the end of the dnstpan,while the other end rests against.the inner-foce ofthe head B, so that; the expansive action of the springwill, when the pan is in use and in place, force it; against thepartition D, when the stud s, projecting from the face ofsaid partitionbelow the bottom of the pan,will sustain it in place.

K is a. plate secured to the bottom of the end B. This plate is castwith a foot, t, designed to project below the end B the same dista-ncethat the wheels .C project belowthe Aio end B'. The plate is alsoprovided with a projecting lug, u, which enters the recess o and forms abearing for the pintle m. The plate is also provided with a sideprojecting hook, 'z-,which sustains the lug lw on the pan. When it isdesired to dump or empty the pan it is drawn towardl the headBcompressing the spring r until released froin the stud s, and the lug1r likewise released from the hook o, when the pan will partially rotateon its pintlcs, as shown in Fig. 2, the lug w ,"assingbetween the hook'c and the body of tue plate to which it is attached. l

A clip, L, is employed to secure the handle M to the case A. yThis clipis secured iu place hy suitable screws,as shown in Fig. 2, midwa ybetween the ends of the sweeper. The clip is provided with socket-s :l:to receive the ,ends'of the bail N, to which the handle is removablysecured. The clip is provided with a curved tongue, y, springing fromone side, and with rigid `stud, c, springing from the opposite side.\Vhen the sweeper is in use the position oi' the handle is shown in Fig.2. When not in use the handle may be raised to a vertical position, asshown in dotted lilies in the same ligure, when the tongue y will holdthe bail in contact with the stud z. A slight p nll will cause thetongue to spring sufficiently to allow the bail to pass over it toregain the iirst position. What I claim as my invention is- 1. In a4carpet-sweeper, the pulley E, having a recess to receive the standard F,and

provided with ashaft` having a polygonalshaped end, in combination withthe divisionplatt l), having a slot, b, smaller than the di- 'stantiallyas described.

ameter ofthe pulley, to allow averticalmovement ot' the pulley and yethold it securely in place when the brush-shaft is removed, sub- 2. .ln acarpet-sweeper, the combination,

' with a revolving brush-shaft, G, of the angular lever I,presscddownward and toward the brush-shaft by the spring k, and theset-screw i, for adjustably sustaining one end of said brush-shaft,substantially as set forth, whereby the spring serves lto press thelever both lownward and inward.

, 3. In a-carpet-sweeper, the combination, with the pulley E, having ashaft with a polygonal-shapcd end', and a recess to receive thestanda'rd F, of the standard l", the brushshai't G, having at oneend asocket, d, to tit' the polygonal end of the pulley-shaft, and at theother end a journal, h, fitting in a recess y' in the spring-lever I,and the spring-lever I. substantially as andfor the purpose specified.

4. In a carpet-sweeper, the pulley E, having a polygonal-shaped endprojectingthrough the partition-plate D, in combination with thevstructed substantially as described, in eombination with the head B andthe pan J, substantially as and for the purpose set forth.

7. The plate K, having the i'oot t, lng u, and hook c, in combinationwith the head 13 and pintle 'm' ot the pan J, substantially as setforth. A

3. ln a carpet-sweeper, the pan J, having pintles m m'and a lug, 1r, incombination with th'e head Il, spring r, and the hook r on the plate K,substantially as described.

y 9. In a carpet-sweeper, the pan J, provided with pinties m m and lug1r, in combination with plate I) and its stop s, head B, with its recesso, spring r, and plate K, substantially as and for-'the purposesspecied.

10. In a carpet-sweeper, a handle secured to the top ease thereof',centrally between the ends` and adapted to have a radial movement, incombination with the xed tongue Z and the spring-tonguey ofthe clip L,for securing it in a vertical position, substantially as and for thepurposes described. f

1l. In a carpet-sweeper, and as a. means ot' securing the handle theretoata pointinidway between the ends Y,there-ot', the clip L, con

structed substantially as described, in combination with thespring-tongue y and hebalc N, as set forth.

12. In alcarpet-sweeper. and as a means-ot' securing and supporting thehandle, the clip L, having recesses to receive the ends of the bail, andprovided with a fixed tongue, Z, and a spring-tongue, y, iu combinationwith the bail N, substantially as described,and for the purposespecified.
